I want the attached probability formula to be coded for both Access VBA and T-SQL (Server 2019 Express). The situation is that I have n numbers in a set (N1, N2, N3 ... Nn). For each number I choose a random number (R1, R2, R3 ... Rn) between 1 and the number (e.g. 0 < R1 < N1, 0 < R2 < N2, 0 < R3 < N3 ... 0 < Rn < Nn ). My quest is to seek the probability for each random number that it should be the largest of the random numbers in the set i.e. P(R1=max(R1 ... Rn)), P(R2=max(R1 ... Rn)) etc. up to P(Rn=max(R1 ... Rn)). I need the code to be able to read just one or multiple groups of numbers from an SQL database. I can set the selection code in SSMS (version 18.12.1). I want your code to read and process the list of numbers from a vertical record set of [Group_ID], [Number_ID]. Each group can contain from 2 numbers up to and including 40 numbers and the numbers within a group are not sequenced though they could be if advantageous. I have been given the attached formula and have tested it against Monty Carlo Simulations and it gives accurate returns. The formula needs to be applied for each number in a group as it calculates probability for each number individually. I want to be able to perform the calculations direct from SSMS and from Access 365 being used as a Front End to the SQL Server database. I want the output to mirror the input so that I can easily make comparisons in Excel. Please ask if further questions and confirm you understand the formula notation ... it took quite a bit of research on my part to understand it as I never went beyond "A" level pure maths! Note: I may want to publish the project on a website in the future but this should only be born in mind in the design if it has minimal impact on your design. I would not want inflated work time (and inflated cost!) at this stage because this is only a 'maybe'. I look forward to receiving considered proposals describing how you will structure this and how you see me applying it. I am surprised to see that PPH is offering this project at a "fixed price" of £363. That is not the case ... they suggested that as a "Budget" not a "fixed price" and I accepted their suggestion on that basis! The price is not fixed ... I have no idea what the cost may be and will decide if this is a project to go forward with depending on the value to me of the cost.

Dear Freelancers, this project is about developing a custom, reusable web scraper with simple GUI to scrape product data by category links from an ecommerce website. The name of the website is https://www.puntronic.com I couldn't find any advanced bot detection techniques like Akamai or Cloudflare. Please have a look at the requirements posted below/the documents attached and give me a short estimation about how long it would take you to develop the script/GUI. Summary and requirements: 1.) The scraper/GUI has to offer an input field into which category links can be entered in to scrape product data from a given category link. 2.) The GUI has to offer input fields for a price range so only products within the given price range get scraped from the entered category link (I couldn't find a price filter on the website, so the script has to do this price filtering by itself). 3.) The script has to offer a GUI (GUI has to offer several input fields to enter fixed strings which are assigned to each line per column (per each link scraped of course) of several of the columns of the resulting CSVs), as well as an input fiel into which a maximum number of products to scrape from each category link within the given price range can be entered. 4.) The scraper has to give out the data by two CSV files: one for the product data, one for the category data. 5.) All in all, 9 columns have to be filled out with scraped data, several other columns have to be filled with values which need to be assignable by the GUI by input fields or with fixed values. 6.) One column will we be a description text which will need some HTML-formatting (bringing elements inside of an element into a random order). 7.) The GUI/script should be easy to use for persons who are non-familiar with python or web scraping tasks. 8.) If needed, it should offer proxy support. 9.) I have little experience in web scraping, so finding the right methods and techniques is up to you, I won't limit you in finding the proper way you want to implement this project. I attached some docments: Please start with Overwiev.pdf (3 pages, one of it is a screenshot), this will give a short summary. If you are still interested, please go on with Details.pdf, it will give you a close view to the requirements. I'm not able to attach CSV files as demo data, but will send them to the person I will aard the project to in the workstream. I'm looking forward to your messages! Thanks and kind regards, Sam
